Certainly! The product of the roots of a polynomial can be found using the relationships between the roots and coefficients.

For a polynomial of the form:

$a_n x^n + a_{n-1} x^{n-1} + \cdots + a_1 x + a_0 = 0$

the product of the roots is determined by the degree and leading coefficient:

Quadratic Polynomial

For a quadratic polynomial $ax^2 + bx + c = 0$ with roots $r_1$ and $r_2$:

• The product of roots $r_1 \cdot r_2$ is given by: $r_1 \cdot r_2 = \frac{c}{a}$

General Case

For a polynomial of degree $n$: $a_n x^n + a_{n-1} x^{n-1} + \cdots + a_1 x + a_0 = 0$ with roots $r_1, r_2, \dots, r_n$:

• If $n$ is even, the product of roots $r_1 \cdot r_2 \cdots r_n$ is: $\frac{a_0}{a_n}$
• If $n$ is odd, the product of roots $r_1 \cdot r_2 \cdots r_n$ is: $-\frac{a_0}{a_n}$
